System and method for performing clear channel assessment for simultaneous transmission in a device implementing multiple wireless protocols. The system may include first and second wireless protocol circuitry configured to generate first and second signals, respectively, for wireless transmission according to first and second wireless protocols, respectively. A first in-band signal strength threshold and a second in-band signal strength threshold may be maintained by the first wireless protocol circuitry. It may be determined whether the first or second in-band signal strength threshold should be used in performing the clear channel assessment. Clear channel assessment may be performed using the determined in-band signal strength threshold. Performing clear channel assessment may include comparing an ambient signal strength on a channel with the determined in-band signal strength threshold. The first wireless protocol circuitry may be configured to determine whether to wirelessly transmit first signals based on the clear channel assessment.

An electronic device capable of transmitting and receiving a mail through an internet usually has from 12 to 20 operation keys inclusive of numerical keys and special keys. In order to input Japanese characters inclusive of “kanji” and special characters as data, complex operations must be executed by changing over the input mode. A portable data terminal as represented by a cellular phone or an electronic device such as a data terminal as represented by a personal computer or a desk top telephone, has such a shape that the first center-line of the first housing and the second center line of the second housing come into agreement and in parallel with each other only in a state where the first housing and the second housing are folded by the hinge.

The present invention relates to a superdirective speaker, and particularly, to a superdirective speaker in which speaker units are disposed and aligned adjacent to one another, and sound outputted from the speaker units overlaps and propagates stepwise, such that the sound may be clearly transmitted over a long distance.

The invention discloses a high-performance flexible nano-communication cable, which includes a cable distribution frame. The front and back of the cable distribution frame are equipped with buckles near one end of the top side, and the side of the cable distribution frame is equipped with five Group communication cable 1, the top surface of the cable distribution frame is equipped with a dust-proof cover plate, and a cable channel is opened on one side of the top surface of the dust-proof cover plate, and there are two holes running through the interior of the cable channel A group of transmission cables, one end of the transmission cable is installed with a cable junction box, the front of the cable junction box is equipped with a waterproof board, and a set of fixing bolts 1 are installed on the front of the waterproof board at the four corners. One side of the junction box is installed in the middle of two groups of communication cables two, one end of the communication cable one is equipped with a connecting plug, and one side of the cable distribution frame is installed with five sets of transfer parts; the present invention considers communication transmission More comprehensive, more secure, stable and accurate communication.

The invention relates to an optical fiber ear and nose cavity mirror which comprises a rigid tube mirror and an eye lens. The rigid tube mirror and the eye lens are coaxially arranged in sequence. The rigid tube mirror comprises a protective tube, an image transmission optical fiber wire and a plurality of light transmission optical fiber wires, wherein a light measuring hole is formed in an outer edge of the protective tube, the image transmission optical fiber wire is used for transmitting an image to the eye lens and is fixedly arranged in the protective tube in a homocentric mode, the light transmission optical fiber wires are used for receiving light rays of peripheral light sources through the light measuring hole, the plurality of light transmission optical fiber wires and the image transmission optical fiber wire are fixedly arranged in the protective tube in parallel and the plurality of light transmission optical fiber wires are evenly distributed around the image transmission optical fiber wire and are separated from the image transmission optical fiber wire. The image transmission optical fiber wire serves as an optical fiber element for transmitting the image, 'zero' thickness performance of an image transmission element is completely used and the plurality of light transmission optical fiber wires are adopted in a matched mode so that the image can be transmitted to the eye lens clearly, image distortion is greatly reduced, structure is simplified and manufacture cost is reduced.

The invention discloses a live broadcast data transmission control method of a big health smart live broadcast hall, which is applied to a 5G live broadcast system, including a video acquisition module, a local processing module and a 5G module, the 5G module is connected to a live broadcast server, and the 5G processing module includes n 5G terminals , each 5G terminal preferentially uses a different 5G operator; the method includes the following steps: collecting video through a video capture module, transcoding through a local processing module, and then dividing the transcoded video into data packets of the same size; Sum verification package generation: data transmission; the live server receives the data strip and verifies the data strip, and verifies the accuracy of the data strip. Through the above settings, multiple 5G terminals can be organically integrated through this method, so clearer single-channel or multi-channel video can be transmitted. At the same time, the setting of the verification data strip can further reduce the error rate of live data transmission and improve the quality of live broadcast. Stability and accuracy of data transmission.
